yes, you can simply set bank1=1. But as I modified this code a while ago to
fix this, I would like you to try some things:
- does it work if you replace the "dcbi" assembler instruction a few lines
before in the invalidate_cache() macro with "dcbf"?
- or if you add a 2nd eieio after dcbi/dcbf?
BTW, which compiler version are you using?
